The service is TERRIBLE!!! My family and I have had their highspeed service, for my gaming addiction, for several years. A year ago i noticed our 10 meg was barely creeping along. after several days of running antivirus scans, speed test after speed test, and ran a trace route to see if the problem was on my end, which was not the case. i called charter. they tried to convince me that it was either A) my laptop or B) my modem. My trace route and antivirus prove these to be false. So they sent a tech out who after 5 min on the phone with his supervisor
he said the problem was with charter but they could not fix the issue because the server portal was not theirs!! Some people i have talked to have said that charter could get in touch with the portal.

Also charter reduced my 10 meg to 6 with out authorization
